I don't really get why you are focused on chambering of all things when it comes to melee, and calling it seal clubbing. Most of the casuals and new players can barely block(if they even tried) and were slaughtered regardless, after you blocked their attack then stabbed them. Most didn't even bother to watch their back, and were backstabbed without even knowing enemies were there. Add on to the fact that many of the "experienced" players would abuse animations and have a seizure while they were feinting making it impossible for the casual to know what the attack was. Chambering wasn't even all that effective, as you had to be close enough to do it, and not mess up while doing it. The higher the ping, the more challenging it is. Against most players, you were just better off blocking then attacking. If they knew how to block, then you started throwing in chambers, more feints, holds, spams, and kicks.
Heck, even most of the experienced players can't block a sword. I am always amazed over the years, at least on NA, how many of the "best" meleers would melt like butter the moment they fought a sword. If you want to know what real seal clubbing is in NW, play cav during a steam sale. i guess most regs never bothered to try fighting people with swords to get better at it. same with cav. Probably one reason why events keep throwing in stupid rules in to try to curtail cav.
Anyways, as olaf said. We will be doing a lot of testing on melee in our builds, and tests with others as the game gets closer to release. Its going to be something we spend a lot of time working on. We will do what we can to make it fun for all players. Something to keep in mind too is that shooting will be deadlier in BCoF. The weapons are more accurate and deadlier in general. So just ramboing around meleeing everyone wont be as easy, unless you are on a part of a map that is more conducive to getting in close to the enemy.(or weather making shooting accurately harder) Shooting and melee are still being worked on, and maps are still being made/worked on. All of which will effect how the game plays.
